LF5D series differential pressure switch/pressure control is normally used in water or oil to control the difference between the outlet tube and inlet tube.
One typical application is to install the valve next to a water or oil system pump by-pass valve line, when the pressure difference rises (or reduces) or the two sides of the tube of the system exceed the setting data of the pressure control, the valve will open or close, so that the system tubes two sides pressure difference is reduced, to reach the system normal circulation.
LF5D series differential pressure controls two sides that have a high sensitivity to each other. When the pressure of two sides of the parts changes, it will allow the switch action to control system equipment, such as a motor drive valve.
